In Pixar's Cars 2, what is the name of the German scientist who leads the Lemons?

Professor Zündapp is the German scientist who leads the Lemons in Pixar's Cars 2.

Professor Zündapp is a small yellow car modeled after a Zündapp Janus microcar. He serves as the principal scientific figure behind the conspiracy targeting the World Grand Prix. The Lemons are a group of outdated and disgruntled cars whose plan uses an untested alternative fuel and electromagnetic weapons.

The character's name references the German motorcycle and vehicle manufacturer Zündapp. In English-language materials, the surname is commonly written with an umlaut as Zündapp, although some databases may simplify the spelling to Zündapp or Zundapp.

Miles Axlerod is the apparent organizer whose public role involves promoting alternative fuel, while Zündapp handles much of the technical and operational work. Finn McMissile and Holley Shiftwell are spies opposing the conspiracy, not members of the Lemons.
